To all whom it may concern:

Be it known that we, Jesse L. Bonus and Joan J. WILSON, citizens of theUnited States of America, and residents of Fernhamville, Calhoun county,Iowa, have invented a new and useful Clutch-Spring Compressor, of whichthe following is a specification.

The object of this invention is to provide an improved device forcompressing a spring held under tension by a pm which it is desired toremove.

A further object of this invention is to rovide an improved deviceadapted for use in dismantling the clutch devices employed on certainmakes of motor vehicles, viz:

Chevrolet 490.

Our invention consists in the construction, arrangement and combinationof elements hereinafter set forth, pointed out in our claims andillustrated by the accompanying drawing, in which- Figure 1 is a sideelevation, partly in section, showing our improved device in osition foruse on a clutch member from w ich it is desired to remove a pin andspring. Fig. 2 is an outer end view of the same. Fig; 3 is a centrallongitudinal section at rig t angles to the showingeof 1, certam partsof the device ing s own in altered position.

In the construction and application of the device the numeral designatesa sleeve 1 which forms a part of one member of a clutch employed on acertain ty e of automobiles, as for instance the hevrolet, said sleevehaving mounted within an expansive coil spring lladapted normally to oldthe coacting clutch member (not 1 shown) out of engagement; said'sleevealso iprovide a dev having a pin 12 mounted transversely therethroughnear one end and forming a stop for the spring 11. The sprin 11 is undertension against the in 12 wh ch renders it difiicult to remove said pinwhen-it is desired to dismantle the clutch devices for any purpose suchas repair, and it is our purpose to ce or tool for compressing saidspring away from said p n to pei'lllli. withdrawal of the pin, afterwhich the spring and other parts of the device may be removed. I Thesleeve 10 also is formed with a pcripheral flange 18 at its end formedwith a plurality of tapped bolt holes 14 arranged in diametricallyopposed pairs.

In the construction'of the tool itself a bar 15 is provided, of a lengthcorresponding approximately to the diameter of the flan e 13, and bolts16, 17 are mounted loose y through opposite end portions of said bar,said bolts being ada ted to be mounted selectively in a pair 0 the holes14v to position the device for use. A collar 18 is swiveled loosely onone side of and at the center of the bar 15, a rivet 19 being mountedthrough the bar and having a head on one end reventing passage throughthe bar and on t e other end a disk upon which the collar is shrunk orotherwise securely fixed. The collar 18 is open at its free end and isadapted to fit loosely within the end of the sleeve 10, and is formedwith diametrically opposite end opening notches or slots 20, 21 adaptedto fit over the pin 12 and permit passage of the end of the collarbeyond said pin and into contact with the end ofthe spring 11. Nuts 22,23 are screwed on the bolts 16, 17, between the heads of said bolts andthe bar 15, and are adapted to be screwed downwardly on said bolts toapply pressure to' said bar.

In practical use the nuts 22, 23 are first loosened on the bolts 16, 17,that is to say moved toward the heads of said bolts. The collar 18 isinserted within the open end of the sleeve 10 and the notches or slrns20, 21

caused to straddle the pin 12. Then the bar 15 is turned, on the rivet19, so that the ends of the bolts 16, 17 may be caused to enter a pairof the bolt holes 14, and said bolts are rife withdrawn rom its seat.Then the device is removed, b loosening the nuts 22 23 and unseating thebolts 16, 17, after which the spri 11g and other parts of the device maybe removed, as desired for the work in hand.

The device may be. used in a similar mannor to compress the sprin forthe insertion of the pin, in assembling te clutch device.
